Harsh parenting triggers teen depression and aggression through distinct rumination paths

A three-year longitudinal study of 878 Chinese adolescents found that harsh parenting (psychological aggression and mild physical punishment) in year 1 increased sadness- and anger-rumination in year 2. Sadness rumination predicted depressive symptoms in year 3, while anger rumination predicted reactive and proactive aggression. In combined analyses, sadness rumination emerged as a broader risk factor for both outcomes, likely because dwelling on sadness drains cognitive resources, with gender patterns showing boys more linked to sadness/depression and girls more to anger/aggression. Limitations include self-report data from private schools in a single region, and lack of baseline rumination, so causality cannot be established. The study suggests adopting less punitive disciplinary methods to protect teen mental health.
